Question 2 The heavier component has to be removed from a gas stream by absorption. The absorption column operates at 2 000 kPa and 40C. The entering oil and gas with its composition and K- values can be found in Table 3. The oil and gas is fed to a stripper with 5 theoretical stages, where the lighter components are stripped by superheated oil. It can be assumed that A and S values can be based on the entering values of L and V, and K- values are constant. Table 3: Ki-values for components Component Lo (mole fraction) V3 (mol fraction) Ki-values CH4 0.2 6.65000 C2H6 0.4625 1.64000 C3H8 0.3 0.58400 C4H10 0.1 0.03125 0.19500 C5H12 0.05 0.00625 0.07130 Non-volatile oil 0.8 0 0.00010 2.1. Draw a schematic diagram that depicts the absorption process showing all the entering and leaving streams with the given information. (2) 2.2. Calculate the molar flowrates of the components entering the absorber in the liquid stream and the effluent gas stream. Tabulate your answers. (8) 2.3. Determine the compositions and flowrates of the vapour (V1) and liquid (L3) streams leaving the absorber. Tabulate your answers in an appropriate table. (20)
